Prognostic analysis of cervical lymph node metastasis in patients with thoracic esophageal squamous cell carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To analyze the prognostic factors of cervical lymph node metastasis (CLN) in thoracic esophageal squamous cell carcinoma (TESCC), and to probe and verify the esophageal carcinoma staging of the 7th edition of American Joint Committee on Cancer (AJCC) TNM staging system.</p><p><b>METHODS</b>A total of 1 715 TESCC patients underwent radical esophagectomy plus three-field lymph node dissection at Fujian Provincial Cancer Hospital between January 1993 and March 2007. 547 patients had pathological metastasis of CLN, and 296 patients received surgery only (S group) and 251 patients received postoperative radiotherapy (S+R group). The prognostic factors were analyzed and the pattern of recurrence and metastases was studied according to the esophageal carcinoma staging criteria of the 7th edition of AJCC TNM staging system.</p><p><b>RESULTS</b>The metastasis rate of CLN was 31.9% for the entire group, 44.2%, 31.5% and 14.4% for the upper, middle and lower TESCC, respectively (P < 0.001). The 5-year overall survival rate of the patients with metastatic CLN was 27.7%, and the median overall survival time was 27.5 months. The 5-year survival rate was 21.3% in the S group and 34.2% in the S+R group, and the median survival time was 21.9 months in the S group and 35.4 months in the S+R group (P < 0.001). Multivariate analysis showed that gender, lesion length in X-ray, N stage, AJCC stage and treatment modality were independent prognostic factors of CLN metastasis in TESCC. Independent prognostic factors for S group included the primary tumor site, pT stage, N stage and AJCC stage, and N stage was an independent prognostic factor for the S+R group.</p><p><b>CONCLUSIONS</b>TESCC with CLN metastasis have a better prognosis after surgery. It supports that cervical lymph nodes belong to regional lymph nodes classified in the 7th edition of AJCC TNM staging system.</p>

Value of postoperative radiochemotherapy for thoracic esophageal squamous cell carcinoma with lymph node metastasis / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To retrospectively compare the efficacy of postoperative radiotherapy (RT) alone with that of postoperative radiotherapy with concurrent chemotherapy (CRT) for thoracic esophageal squamous cell carcinoma (EPC) with positive lymph nodes, and to evaluate the clinical value of RT + CRT.</p><p><b>METHODS</b>304 EPC patients underwent esophagectomy with three-field lymph node dissection had pathological lymph node metastases, but no hematogenous distant metastasis. Among them, 140 cases underwent postoperative RT alone, and 164 cases underwent postoperative CRT. The dose of irradiation was 50 Gy, and the chemotherapy regimen was taxol and cis-platinum, and a cycle was 21 days.</p><p><b>RESULTS</b>The 1-, 3- and 5-year total survival rates of the whole group were 90.1%, 56.6% and 43.3%, respectively, with a median survival time of 49.7 months. The 5-year overall survival rates of the CRT and RT groups were 47.4% and 38.6%, respectively (P = 0.030), with a median survival time of 53.5 and 41.7 months, respectively (P = 0.030). The overall survival rates of the patients who underwent 1, 2, 3, 4 cycles of chemotherapy were 24.4%, 53.0%, 58.1% and 43.3%, respectively (P = 0.007). Among them, the 5-year total survival rate of patients with 2-4 cycles of chemotherapy was significantly better than that of patients who underwent one cycle of chemotherapy (P = 0.001). Univariate analysis showed that number of metastatic lymph nodes, pT stage, therapeutic regimen and number of chemotherapy cycles were significantly correlated with the prognosis of the patients (P < 0.05 for all). Multivariate analysis showed that number of metastatic lymph nodes, pT stage, and number of chemotherapy cycles were independent prognostic factors of the patients (P < 0.05 for all). Early toxic effects including neutropenia, radiation esophagitis, and gastrointestinal effects were significantly more severe in the CRT group than that in the RT group (P < 0.05), however, there were no significant differences of late toxic effects between the two groups (P > 0.05).</p><p><b>CONCLUSION</b>Postoperative CRT for thoracic EPC with positive lymph nodes can improve the survival rate, with tolerable adverse effects.</p>

Clinical analysis of the characteristics of cervical lymph node metastasis in thoracic esophageal squamous cell carcinoma / 中国癌症杂志

Background and purpose: Lymph node (LN) metastasis of esophageal cancer of neck rate higher, but there is little bulk reports. This article aimed to analyze the characteristics of cervical lymph node metastasis (CLN) in thoracic esophageal squamous cell carcinoma (TE-SCC) and the clinical role. Methods:A total number of 1 131 TE-SCC patients underwent radical esophagectomy plus three-ifeld lymph node dissection at Fujian Provincial Tumor Hospital between Jan. 1993 to Dec. 2003, during which, 367 patients had pathological metastasis of CLN. Results:The metastatic rate of CLN was 33.2%for the entire group, 43.7%, 33.0%and 16.0%for the upper, middle and lower TE-SCC respectively. Single factor analysis showed that the metastatic rate of CLN was relevant with the tumor site, pathological differentiated degree, lesion length showed in X-ray, pT stage and the number of CLN (P<0.05). But multivariate regression analysis showed that the metastatic rate of CLN was just relevant with the tumor site, pT stage and the number of CLN (P<0.05). Metastasis of cervical paraesophageal lymph nodes was the most common, and Background and purpose: Lymph node (LN) metastasis of esophageal cancer of neck rate higher, but there is little bulk reports.

But multivariate regression analysis showed that the metastatic rate of CLN was just relevant with the tumor site, pT stage and the number of CLN (P<0.05). Metastasis of cervical paraesophageal lymph nodes was the most common, and supraclavicular lymph node metastasis was next, and metastasis of cervical profound lymph nodes and retropharyngeal lymph nodes were rare. The ratio of the number of CLN occupied the sum of the segmental CLN were 57.7%, 32.0%and 10.0%for the upper, middle and lower TE-SCC respectively (P<0.05). Right CLN of each segmental TE-SCC was more than left CLN. Conclusion:Independent factors on CLN in TE-SCC are the tumor site, pT stage and the number of CLN. Metastasis of cervical paraesophageal lymph nodes is the most common, and supraclavicular lymph node metastasis is next, and metastasis of cervical profound lymph nodes and retropharyngeal lymph nodes are rare.

Long-term results of nasopharyngeal carcinoma treated with radiotherapy:1706 cases report / 中华放射肿瘤学杂志

Objective To analyze the long-term efficacy,prognostic factors and radiation sequela of nasopharyngeal carcinoma(NPC)treated with radiotherapy at the end of last century.Methods From January 1995 to December 1998,1706 newly diagnosed NPC patients treated with radiotherapy were included in the retrospective clinical analysis.There were 1081 patients treated with radiotherapy alone,625 with two to three circles of chemotherapy(5-Fu and DDP)before radiotherapy,23 with thermotherapy during radiotherapy and 162 with braehytherapy by 192Ir after external beam radiation.Results The 5-year overall survival. local control survival and disease-free survival rates were 67.60%.84.20%and 64.22%.respectively.The 5-year survival of patients with stage Ⅰ,Ⅱ,Ⅲand Ⅳ(the Fuzhou Staging,1992)were 100%,75.93%,66.47%and 49.34%.respectively.Cox regression analysis showed that the TNM classification,radiotherapy discontinuance,chemotherapy,sex,age and anemia before radiotherapy were the significant factors of survival.Conclusions Our experience shows that the main factors for the long term survival of NPC patients after radiotherapy are early TNM stage,young age,female,non-anemia before radiotherapy, radiotherapy continuance and chemotherapy.
